Abstract
A process for deactivation of an olefin oligomerization catalyst is described, including contacting a catalyst composition with a catalyst quenching medium to form a deactivated catalyst composition, and recovering excess catalyst quenching medium. The catalyst quenching medium includes an alcohol having at least 6 carbon atoms, an organic amine, an amino alcohol, or a combination comprising at least one of the foregoing. The catalyst quenching medium is present in a molar ratio of catalyst quenching medium to catalyst of at least 3:1. A process for the oligomerization of an olefin is also described, including feeding the olefin, a solvent, and a catalyst composition into a reactor, oligomerizing the olefin in the reactor to form a reaction product stream including linear alpha olefins, solvent, and the catalyst composition, and contacting the reaction product stream with a catalyst quenching medium.
